Title:
A VEHICLE POWERTRAIN SYSTEM, A VEHICLE, AND A METHOD FOR OPERATING A VEHICLE POWERTRAIN SYSTEM
Document Type and Number:
WIPO Patent Application WO/2020/248882
Kind Code:
A1
Abstract:
A vehicle powertrain system (1) comprising an electric motor (2), a planetary gear set (3), a coupling unit (4), and a differential unit (5) is disclosed, wherein the electric motor (2) is drivingly connected to the planetary gear set (3) via a motor shaft (6) extending in an axial direction (A), and wherein the planetary gear set (3) is operably connectable to the differential unit (5) via the coupling unit (4), wherein the powertrain system (1) further comprises an idle gear wheel (9) and a differential drive gear wheel (10) arranged on the differential unit (5), wherein the coupling unit (4) is arranged for selectively transferring torque to the idle gear wheel (9), and wherein the idle gear wheel (9) and the differential drive gear wheel (10) are arranged to drivingly interact with each other for transferring torque from the electric motor (2) to the differential unit (5), via the planetary gear set (3) and the coupling unit (4).
